Introduction 

 

Thank you for choosing the Adastra L50U megaphone with USB/SD player. This product is designed to 

offer convenient and easy operation for a wide range of portable public address requirements. Please use 
the following instructions to gain the best results from your megaphone. 

 

Safety  

 
The L50U megaphone can produce high sound pressure levels at close quarters. Please be aware not to 

aim the horn flare toward listeners at close proximity, which may risk damage to the listeners’ hearing.

 

The L50U operates from 10 x 

D

” cell

 batteries. It is advised to use alkaline or NiMH batteries and to 

remove these when not in use for long periods of time. Some batteries can leak fluids which are corrosive 
and can cause damage to the internal circuitry. 

 

Positioning during operation 

 
When in use, the handle of the megaphone should be held firmly with the flare facing toward the 

audience. Alternatively, the megaphone can be slung under the arm using the supplied shoulder strap or 
free-standing on a flat surface. An M8 threaded insert is also provided for mounting onto a plate or stand. 

 

Cleaning 

 

The housing is water resistant and can be cleaned with a damp cloth. Do not use detergents or solvents 
on the housing and take care not to allow liquids to get inside the housing or the battery compartment. 

 

Setting up 

Before operating the L50U megaphone, it 

will be necessary to load it with 10 x “D” 

cell batteries. Alternatively, a 12Vdc 
supply can be connected to the 12Vdc 
input on the side panel. 
 
To access the rear battery compartment, 
press down the latch at the rear of the 

housing marked “PUSH OPEN” and allow 

the rear cover to fold down. Remove the 
plastic insert from the battery 
compartment and load 2 batteries into 
each of the 5 cylinders as shown in the 
diagram. Replace the insert and close the 
cover. 
 
Note: the pairs of batteries are loaded 
with alternate polarity as imprinted on the 
outside of the insert.
